Brominated flame retardants (BFRs) are mixtures of man-made chemicals that are added to a wide variety of products, including for industrial use, to make them less flammable. They are used commonly in plastics, textiles and electrical/electronic equipment. Scientists link flame retardants and reduced human fertility.

brominated - Swedish translation – Linguee

Polybrominated diphenyl ethers (PBDEs), a common class of brominated flame retardants (BFRs), are a ubiquitous part of our built environment. For many years, these flame retardants have improved public safety by reducing the flammability of everyday items including computers, furnishings and mattresses.

In 2003 California passed a state-wide ban on flame retardant chemicals known as polybrominated diphenyl ethers, or PBDEs.

They are found Flame Retardants Still Ubiquitous Despite Phase-Out, Bans PBDEs first came into widespread use after California passed fire safety standards for furniture and certain other products in 1975. Thanks to the size of the Californian market, flame retardants soon became a standard treatment for furniture sold across the country. Since states started banning PBDE flame retardants in the early 2000s, scientists have recorded decreasing levels of PBDEs in the following Puget Sound species: Harbor seals – on Gertrude Island in Southern Puget Sound (1, 2) Pacific herring – declines seen in 4 stocks sampled around Puget Sound (3, 4), Many halogenated flame retardants with aromatic rings, including most brominated flame retardants, are likely thyroid hormone disruptors. The thyroid hormones triiodothyronine (T3) and thyroxine (T4) carry iodine atoms, another halogen, and are structurally similar to many aromatic halogenated flame retardants, including PCBs, TBBPA, and PBDEs.
